I had an interview with HR, and when I had the interview with the manager, he didn't connect me, so I had to contact HR. He finally connected, said the timing was wrong, and the interview was a bit rushed. I then had another interview with two other managers. I waited for a response, contacted HR, and received no response. I received a generic email stating that they would not continue with my application. It's okay if I don't get selected for the position, but just as I took the time to prepare for interviews, research the company, etc., at least I expected the same from HR by providing feedback and not a generic email. Very unprofessional.
